lol, the Jews in Portugal didn't come from fukking Portuguese African colonies no more than the Moors had come from there. Jews were in Portugal LONG before the Portuguese had African colonies. You have shyt completely ass-backwards.
Jews in Portugal had come from immigration from the Middle East and North Africa, where there had been travel to and from the Iberian peninsula for 1500 years before the Portuguese ever went to sub-saharan Africa. That's why Moroccan Jews are relevant, not some colonies that didn't even exist.
Cush is Ethiopia and Tacitus says Ethiopia. We KNOW there are Jews in Ethiopia and we know there were Ethiopians in Israel, that's confirmed in the Biblical record, in Ethiopian cultural record, and in genetic testing. Now you've confirmed it in Tacitus too.
You somehow want to move the goalposts and claim those Ethiopian Jews were actually West African Jews, with no evidence whatsoever, despite the fact that there is ZERO Biblical evidence, ZERO historical evidence, ZERO cultural evidence, and ZERO genetic evidence for Jews anywhere in West, Central, or South Africa (outside of the Lemba tribe, who were a unique event and who don't associate with Hebrew Isrealites and their bullshyt).
Until 1886, no one thought that Black people were the "true Israelites". African people didn't think that, Black Christians didn't think that, there was no historical record of it, no cultural record of it, no religious record of it, and the genetic studies since then have confirmed that it isn't true. The idea was literally invented by a false prophet in 1886 who was riffing on the "Black people got released from slavery like the Hebrews got released from slavery!" sermons that were popular as a metaphor, and that one guy tried to spin it into reality. And he didn't claim a historical or Scriptural basis for his belief, he claimed that GOD told him in a revelation it was true and also claimed God told him that Jesus was going to come back in the year 2000.
You're literally following the made-up beliefs of a proven false prophet whose fans have spent a century trying to juelz why his nonsense doesn't match any evidence and why his prophecies failed to come true.
